Six-month healing of the nonocclusive coronary anastomotic connector in an off-pump porcine bypass model.
This pilot study evaluates the anastomotic healing of the Excimer Laser Assisted Nonocclusive Anastomosis coronary connector at 6 months in a porcine off-pump coronary artery bypass (OPCAB) model. ⋯ In this pilot study, the Excimer Laser Assisted Nonocclusive Anastomosis coronary connector showed an excellent healing response on the long-term in the porcine OPCAB model. Hence, this new concept might be a potential alternative to hand-sutured anastomosis in (minimally invasive) OPCAB surgery.

Aortic valve replacement via right minithoracotomy versus median sternotomy: a propensity score analysis.
The aim of this study was to define the relative role of a right minithoracotomy (RT) versus standard median sternotomy (ST) for open aortic valve replacement (AVR). ⋯ Given the biases of retrospective propensity-adjusted analysis, these data suggest that RT AVR is a safe alternative to ST AVR in selected patients, with advantages of avoiding sternotomy with associated bleeding, transfusion, and delayed wound healing, at the expense of longer pump and clamp times.

Impact of sex on the risk to develop contrast-induced nephropathy after transcatheter aortic valve implantation.
Contrast-induced nephropathy (CIN) is the third most common cause of acute renal failure and is associated with increased morbidity and in-hospital mortality. Some recent studies identified female sex as a risk factor of CIN. The aim of this study was to determine the relative impact of female sex on the development and clinical outcome of CIN in patients with preexisting renal impairment after transapical transcatheter aortic valve implantation (TAVI). ⋯ Women with preexisting renal impairment are at higher risk than men for CIN, with resultant higher early mortality after transapical TAVI.
